compile 32-bit gdkglext on amd64

spuzzzzzzz · 10-08-2004, 09:36 PM

I'm trying to compile a 32-bit version of gtkglext on my 64-bit machine. My gcc supports multilib, but there is a really annoying step in the build process where it insists on linking in .so files from /usr/lib:

Code:

gcc -m32 -shared  .libs/gdkglversion.o .libs/gdkglinit.o .libs/gdkglquery.o 
.libs/gdkglconfig.o .libs/gdkglcontext.o .libs/gdkgldrawable.o .libs/gdkglpixmap.o 
.libs/gdkglwindow.o .libs/gdkglshapes.o .libs/gdkglglext.o .libs/gdkglenumtypes.o 
-Wl,--whole-archive x11/.libs/libgdkglext-x11.a -Wl,--no-whole-archive  -L/usr/X11R6/lib 
-L/usr/lib -L/usr/lib32 -L/usr/X11R6/lib32 /usr/lib/libGLU.so -lGL -L/usr/X11R6/lib64 -lXmu
 -lXt -lSM -lICE /usr/lib/libgdk-x11-2.0.so /usr/lib/libgdk_pixbuf-2.0.so 
/usr/lib/libpangoxft-1.0.so /usr/lib/libpangox-1.0.so /usr/lib/libpango-1.0.so 
/usr/lib/libgobject-2.0.so /usr/lib/libgmodule-2.0.so -ldl /usr/lib/libglib-2.0.so -lm  
-Wl,--export-dynamic -Wl,-soname -Wl,libgdkglext-x11-1.0.so.0 -Wl,-version-script 
-Wl,.libs/libgdkglext-x11-1.0.ver -o .libs/libgdkglext-x11-1.0.so.0.2.4
/usr/lib/libGLU.so: could not read symbols: Invalid operation

I want to replace /usr/lib/* with /usr/lib32/*. If I do it manually, it works; I can create .libs/libgdkglext-x11-1.0.so.0.2.4. If I try to resume the build process, though, it insists on trying to build .libs/libgdkglext-x11-1.0.so.0.2.4 again (and it fails). Why does it insist on linking these libraries at compile time instead of runtime? And I can't see where that command is coming from in the Makefile. "grep /usr/lib/libGL *" and "grep /usr/lib/libGL gdk/*" don't find anything. Help anyone?

post the Makefile somewhere perhaps i can see how to fix ??
i gave up on trying to figure out why these libtool troubles crop up sometimes
and just go for hacking the makefile

Here's the Makefile.am (from the gdk subdirectory of the source tree). The Makefile is really long and ugly and this forum wouldn't let me post it (too long). If you can't find a problem in here, I can split up the Makefile over two posts if you want.

Code:
